As shown in FIG. 4, the handset 2 includes a connection detection section 201, a mode determination section 202, a transmission section 203, and a mode setting section 204. The functions of each component (201 to 204) of the slave device 2 are realized by the CPU 22 in FIG. 1 executing a performance mode setting program stored in the storage device 27 or the ROM 24.

The connection detection unit 201 detects whether the headset 50 is connected to each of the main terminal 31 and the sub-terminal 32. The mode determining section 202 determines the performance mode based on the detection result of the connection detecting section 201. Specifically, when it is detected that the headset 50 is connected to the main terminal 31 and the headset 50 is not connected to the sub-terminal 32, the mode determination unit 202 determines the performance mode to be the solo mode. do. Note that the mode determining unit 202 determines the performance mode to be the solo mode when it is detected that the headset 50 is not connected to the main terminal 31 and the headset 50 is connected to the sub-terminal 32. Good too. On the other hand, if it is detected that the headset 50 is connected to each of the main terminal 31 and the sub-terminal 32, the mode determination section 202 determines the performance mode to be the duo mode. The transmitting unit 203 transmits a notification of the performance mode determined by the mode determining unit 202 to the base unit 1 through the communication network 5. The performance mode notification is a solo mode setting notification or a duo mode setting notification. The solo mode setting notification and the duo mode setting notification include the handset identifier assigned to the handset 2. As will be described later, notification of the performance mode is performed by transmitting and receiving performance mode notification data. Further, the transmitter 203 transmits audio data based on the acoustic signals input from each headset 50 and performance data provided from the electronic musical instrument 4 to the base unit 1 .

Each solo icon IC4 represents that the electronic musical instrument 4 connected to the slave unit 2 is set to the solo mode by connecting the headset 50 to the sub-terminal 32 of the slave unit 2.

FIG. 6 is an enlarged view of the Duo Icon IC2. In the duo icon IC2, for example, the names N1 and N2 of the performers are displayed below the portraits P1 and P2 of the two people. As a result, the teacher using the base unit 1 can confirm that the electronic musical instrument 4 connected to the slave unit 2 is set to duo mode, and that the two performers of the electronic musical instrument 4 connected to the slave unit 2 You can easily recognize the name. Note that the name of the performer may be displayed under the portrait P1 of the solo icon IC1, and the name of the performer may be displayed under the portrait P2 of the solo icon IC4.

When performance data from the left or right keyboard range or audio data from one of the headsets 50 is transmitted from the handset 2 to the base unit 1, the display 16 displays identification information. Based on this, the portrait P2 corresponding to the source of the performance data or audio data is displayed in a manner different from the other portrait P1. For example, the portrait P2 corresponding to the source of the performance data or audio data is displayed in a different color from the other portraits P1, or is displayed blinking. The portrait P2 corresponding to the source of the performance data or audio data may be displayed to have a different shape from the other portraits P1. Here, the generation source refers to either the left or right keyboard area, either the main terminal 31 or the sub-terminal 32, or the left player's headset 50 or the right player's headset 50. Corresponds to either one.

When performance data from the left and right keyboard ranges or audio data from both headsets 50 is transmitted from the handset 2 to the base unit 1, the display 16 displays the performance data or Portrait images P1 and P2 corresponding to the source of the audio data are displayed in a manner different from that when the performance data and audio data have not been transmitted.

(6) An example of a performance mode setting method Next, a performance mode setting method using the master unit 1 and slave unit 2 will be explained. The performance mode setting method includes processing of the slave device 2 and processing of the master device 1. FIG. 7 is a schematic diagram showing an example of performance mode notification data. FIG. 8 is a flowchart showing the processing of the handset 2. FIG. 9 is a flowchart showing the processing of the base device 1. The process in FIG. 8 is performed by the CPU 22 in FIG. 2 executing a performance mode setting program stored in the storage device 27 or ROM 24. The process in FIG. 9 is performed by the CPU 12 in FIG. 2 executing a performance mode setting program stored in the storage device 17 or ROM 14.

The performance mode notification data MD shown in FIG. 7 is, for example, a MIDI (Musical Instruments Digital Interface) message. The performance mode notification data MD includes a timestamp 301 indicating the current time, a handset identifier 302, a mode switching instruction 303, and numerical data indicating solo/duo 304, respectively. When the solo/duo 304 is a numerical value indicating "solo", the performance mode notification data MD is a solo mode setting notification. When the solo/duo 304 is a numerical value indicating "duo", the performance mode notification data MD is a duo mode setting notification.

As shown in FIG. 8, the connection detection unit 201 in FIG. 4 detects whether the headset 50 is connected to each of the main terminal 31 and the sub-terminal 32 (step S1). If the connection of the headset 50 is not detected, the mode determination unit 202 waits until the connection detection unit 201 detects the connection of the headset 50.

If the connection of the headset 50 is detected, the mode determination unit 102 determines whether the headset 50 is connected to both the main terminal 31 and the sub-terminal 32 (step S2). If the headset 50 is connected to both the main terminal 31 and the sub-terminal 32, the mode setting unit 204 sets the electronic musical instrument 4 to duo mode (step S3). The transmitting unit 203 transmits a duo mode setting notification to the base unit 1 via the communication network 5 (step S4).

The mode determining unit 102 determines whether the headset 50 has been removed from the handset 2 (step S5). If none of the headsets 50 have been removed from the handset 2, the mode determination unit 102 stands by. If at least one headset 50 has been removed from the handset 2, the mode determination unit 102 determines whether both headsets 50 have been removed from the handset 2 (step S6). When both headsets 50 are removed from handset 2, transmitter 203 transmits a training end signal indicating the end of the training to base unit 1 through communication network 5 (step S7), and returns to step S1. .

If the headset 50 is not connected to both the main terminal 31 and the sub-terminal 32 in step S2 (the headset 50 is connected to one of the main terminal 31 and the sub-terminal 32, and the headset 50 is not connected to the other) case), the mode determination unit 202 sets the electronic musical instrument 4 to solo mode (step S8). In this embodiment, the mode setting unit 204 sets the electronic musical instrument 4 to solo mode when the headset 50 is connected only to the main terminal 31. Note that the mode setting unit 204 may set the electronic musical instrument 4 to solo mode when the headset 50 is connected only to the subterminal 32. The transmitter 203 transmits a solo mode setting notification to the base unit 1 via the communication network 5 (step S9).

The mode determining unit 202 determines whether the headset 50 has been removed from the handset 2 (step S10). If the headset 50 has not been removed from the handset 2, the mode determination unit 202 returns to step S1. If the headset 50 is removed from the handset 2, the mode determination unit 202 proceeds to step S7 and transmits a training end signal to the base unit 1 through the communication network 5.

If both headsets 50 have not been removed from the handset 2 in step S6 (if only one headset 50 has been removed from the handset 2), the mode determination unit 202 proceeds to step S8.

In this way, when two headsets 50 are connected to the handset 2, the electronic musical instrument 4 corresponding to the handset 2 is set to Duo mode, and the handset 2 is connected to the Duo mode. A mode setting notification is sent. On the other hand, when only one headset 50 is connected to the slave unit 2, the electronic musical instrument 4 corresponding to the slave unit 2 is set to solo mode, and the slave unit 2 sets the solo mode to the base unit 1. A notification will be sent.

Receiving section 101 of base unit 1 in FIG. 4 receives the performance mode notification transmitted from slave unit 2. As shown in FIG. 9, the mode determining unit 102 determines whether the receiving unit 101 has received a duo mode setting notification as a performance mode notification (step S21). When the receiving unit 101 receives the duo mode setting notification, the handset identification unit 103 identifies the handset 2 that has transmitted the duo mode setting notification based on the handset identifier included in the duo mode setting notification (step S22). The display control unit 104 causes the display 16 to display the duo icon IC2 corresponding to the handset 2 (step S23).

The mode determining unit 102 determines whether the receiving unit 101 has received the training end signal (step S24). When the receiving unit 101 receives the training end signal, the display control unit 104 displays the handset unused icon IC0 corresponding to the handset 2 on the display 16 (step S25), and returns to step S21.

If the receiving unit 101 has not received the duo mode setting notification in step S21, the mode determining unit 102 determines whether the receiving unit 101 has received the solo mode setting notification (step S26). When the receiving unit 101 receives the solo mode setting notification, the handset identification unit 103 identifies the handset 2 that has transmitted the solo mode setting notification based on the handset identifier included in the solo mode setting notification (step S27 ). The display control unit 104 displays the solo icon IC1 corresponding to the handset 2 on the display 16 (step S28), and proceeds to step S24.

If the receiving unit 101 has not received the solo mode setting notification in step S26, the mode determining unit 102 proceeds to step S25.

In this manner, when the electronic musical instrument 4 corresponding to the slave unit 2 is set to the duo mode, the duo icon IC2 corresponding to the slave unit 2 is displayed on the display 16 of the base unit 1. When the electronic musical instrument 4 corresponding to the handset 2 is set to the solo mode, a solo icon IC1 corresponding to the handset 2 is displayed on the display 16 of the base unit 1. When the electronic musical instrument 4 corresponding to the handset 2 is not set to the duo mode or the solo mode, a handset unused icon IC0 corresponding to the handset 2 is displayed on the display 16 of the base unit 1.

Note that the order of steps S3 and S4 in FIG. 8 may be reversed, or steps S3 and S4 may be performed simultaneously. Further, the order of steps S8 and S9 in FIG. 8 may be reversed, or steps S8 and S9 may be performed simultaneously.

(7) Effects of Embodiment According to the present embodiment, each handset 2 is provided corresponding to each electronic musical instrument 4 and can communicate with the base unit 1. A plurality of students can each connect the headset 50, which is a receiver, to the main terminal 31 and the sub-terminal 32, which are the connection parts of the handset 2. The mode setting unit 204 determines whether a plurality of headsets 50 are connected to the handset 2. If it is determined that a plurality of headsets 50 are connected to the handset 2, the mode setting unit 204 sets the electronic musical instrument 4 connected to the handset 2 to duo mode. Thereby, a plurality of students can perform using one electronic musical instrument 4 by connecting a plurality of headsets 50 to the handset 2. Therefore, it becomes possible for a plurality of people to smoothly start playing the electronic musical instrument 3.

Further, since the transmitting unit 203 transmits the duo mode setting notification to the base unit 1, the teacher can easily recognize that the electronic musical instrument 4 corresponding to the slave unit 2 has been set to the duo mode.
